FFICE ARCH. SUPPORT AppIica-tion filed March 28, 1928, Serial No. 265,365, and. in Canada April 2, 1927.

across an open frame, and the object of the present invention is to improve the construction of such an arch support with a View to thereby increase its usefulness. To this end, I provide special hooks for attaching the one end of said coiled springs to the member (plate) for varying the tension of said springs,inserting said hooks in apertures provided in said tension varying member. Moreover, in the sock against which the frame is placed, ll provide along one side thereof, a slot permitting the frame to be readily adjusted to various positions to suit the particular foot for which the arch support is intended. fidditi-onal improvements will appear from the following detailed description with reference to the annexed drawing in which Fig. 1 is a top plan view of the open frame for carrying the coiled springs, Fig. 2 a bottom plan view thereof with the springs shown in position thereon, Fig. 3 a side view showing the tension varying member or plate, Fig. 4 a sectional view through the frame and the tension varying plate, Fig. 5 a top plan view of the sock with the arch support in position thereon, Fig. 6 a detail view of the two screw-spindles for adjusting the tension varying plate and Fig. 7 a fragmentary view of the sock seen from its underside to more clearly show the slot for the adjustment of the arch support. The arch support proper comprises the open metal frame 1 of traps zoidal shape slightly convex to conform to i the concave contour ofthe sole of the human which is provided in the center with a slot 7 (Fig. 3) into which enters a guide-pin 8 secured in the upturned portion 1 The elevatmg member 6 has a plurality of perforations shown at 9, and it is made with two inclined edges or shoulders 10, 11.

fit 12 are shown eight coiled springs, (the numberofthcse springs can, of course, be varied), the ends of whichsprings engage notches 13 provided along one edge of frame 1, while the other ends of the springs are attached to hooks 14-, which are detachably secured in the perforations 9 in the elevating member 6. (Fig. 3.)

The tension of the coiled springs 12 can be varied by a raising or lowering of the elevating member 6. To this end, two screwspindles 15 and 16 are provided, extending along the upturned portion 1 of the frame and with their ends guided in guiding members 17 and 18 respectively disposed in the opening or recess 5 of plate 2. The screw spindles engage lugs 19 and 20 respectively having corresponding female threads and projecting through slots 21 and 22 in the upturned portion 1 of frame 1, adapted to move in these slots in contact with the inclined edg 10 and 11 respectively of the elevating me. ibcr 6. 1 At their outer ends, the screw spindles are nrovided with finger pieces 23 and respectively whereby they can be rotat in eit 161 direction.

.l LS shown in Fig. 5, the arch support is placed against the underside of a sock 25 made of leather, or other suitable material. This seek is provided with a longitudinal si ,t 26' in which the arch support is adjustably held by pivot pins 27, 28 secured in holes 919, 30 respectively in the frame 1. This arengement permits the arch support to be easily adjusted to the correct position along the sock to suit the foot of the wearer. Preferably the slot 26 is reinforced by a thin metal strip shown at 31 in Fig. 7.

At 32 in Figs. 1 and 2 are shown the aper- 'tures in the upturned portion 1 for the insertion of the lugs engaged by the screw Spindles.

WVhen both screw spindles are rotated in a direction to move the lugs outwardly, that is, away from thecenter of the upturned portion 1, the lugs moving along the inclined edges of the elevating member 6 will gradually raise the same to a'position, in which the tension of the coiled springs is increased with the result of imparting a greater resistance to the arched portion of the sock. When, on the other hand, the screw spindles are rotated in the other direction, the tension of thesprings is more and more relaxed.

' Since two screw spindles are provided independent ofeach other, it will be seen that the tension of one-half of the springs can be altered so as to adjust only portion of the ,sock.

At 35 is shown a meta-tarsal attachment held in a slot 33 of the sock so as'to be adjustable therein by a stud 34;.

the corresponding The lateral'portions of the open frame 1 are provided with corrugations 35 and 36 imparting to the frame greater rigidity.

The arch support is placed against the underside of the sock 25 as shown. in Fig. 5,

the pins 27 and 28 being inserted into the slot, 26 in the sock so that the frame 1 can be adjusted in either direction in the longitudina'l'axis of the sock.

' r I claim: I V V T 1. An arch support, comprising arslightly convex open frame having an upturned portion, and slots extending along said portion, a reinforcing plate for said upturnedpor- 'tion having a recess therein, an elevating member having oppositely inclined edges mounted to slide up and down relative to said upturned portion, resilient members connecting said elevating member with the g opposite side of said frame, interiorly thread- I :ed blocks movable in said slots in contact with the inclined edges of said elevating member thereby varying its position relative to said upturned portion and thereby varying the tension of said resilient members, two screw spindles engaging said blocks, bearing mem- .bers, for said :screw spindles received in the recess in said reinforcing plate, and means for rotating-said screw spindles independently of each other. 7 r

2. In an arch support of the type described, the combination with a slightly convex open frame, having an upturned portion, of an elevating member mounted to slide up and down on said upturned portion relative thereto, means for varying the position of said member, coiled springs connecting said elevating memberwith the opposite side of said frame, and connecting'hooks between the ends of said springs and said elevating member adapted to engage apertures in said member.

3. In combination with a sock having a
